The DREO Electronic Warfare Engagement Simulation Facility

The Electronic Warfare Engagement Simulation Facility (EWESF) is a research facility used at the Defence Research Establishment Ottawa (DREO) to assess the performance of electronic warfare systems. The facility is designed to evaluate the effectiveness of radar jamming hardware and jamming techniques using a hardware-in-the-loop configuration. Actual radar jamming equipment is interfaced to the facility and is stimulated by radar signals from a victim radar. The jammer response to the threat radar signal is radiated into the EWESF anechoic chamber to degrade the performance of the radar. The radar performance can be monitored and the jamming techniques can be modified until a technique design is obtained which maximizes the radar degradation. This paper describes the basic design and operation of the EWESF
